The Faculty name which our laboratory belongs to is changed to
Department of Precision Engineering
due to the reorganization from Apr. 2020.

Humanity is confronted with many global-scale issues that include depletion of fossil energy and other natural resources, food shortage and population explosion, climate change and natural disaster, and urban development and poverty. Technology has the potential for significant impact to overcome these challenges and build a sustainable society. In response to the hopes, dreams, and wishes that people find through family, friends, and community, we believe that science and technology should be developed to enable humanity to responsibly coexist and thrive with nature in environmental harmony. To realize a sustainable and prosperous future, we aim to facilitate technological innovation by designing new materials, combining dissimilar materials, and introducing new structures with wide-range of capabilities contributing to next-generation of green nanoelectronics.
